Title: Improvements in or relating to culinary mixing machines
Inventor: PANISSET DENIS SYDNEY
IPC: A47J43/08
Filed: 1951-10-02
Abstract: 730,007. Reverse gearing. SIMPLEX ELECTRIC CO., Ltd. Sept. 29, 1952 [Oct. 2, 1951], No. 22875/51. Class 80 (2). [Also in Group II] A culinary mixing-machine having its mixing spindle 12 driven from an electric motor 11 through change-speed gearing in which drive is selectively transmitted through one of a plurality of gear trains, is characterized by the gearing containing an associated clutch member (or members) 29 which, by screw-threaded means 30, utilizes the transmitted torque to maintain itself in engagement with its cooperating clutch part (or parts). In the form shown, the motor 11 drives a shaft 16 formed with a worm 28 engaged on its opposite sides by worm wheels 26, 27 which are accordingly rotated in opposite directions, these worm wheels being mounted on layshafts 25, 24 to which are secured, respectively, a small pinion 22 above the worm wheel 27, and a large pinion 23 below the worm wheel 26. The pinions 22, 23 mesh gears 18, 19 rotatable on a driven shaft 17 but clutchable thereto by a bush 29 on a screw thread 30 on the driven shaft. The. bush 29 thus selects whichever .of the two ratios is required, change of ratio also reversing the direction of rotation of the driven spindle 17, which is connected through a knob 33 to the mixing spindle 12. The bush engages the gears 18, 19 either frictionally, as shown, or positively, the hand of the screw thread 30, in combination with the opposite directions of rotation of these gears, ensuring that the transmission of torque tightens the engagement between the bush and co-operating gear. The direction of rotation of the driven shaft is varied by switching off the motor 11 and then turning the knob 33 on the driven shaft by hand to change the engagement of the bush 29 with the driven gears; to ensure that the bush does not rotate with the driven shaft, instead of screwing there along, a plunger 34 may be depressed to engage with it. The bush may alternatively be rotated to reverse the gear by a separate rotary selector member, not shown, normally out of engagement therewith but brought temporarily into engagement for this purpose, the member being controlled externally of the mixer. According to the Provisional Specification, the change-speed gear can be applied to domestic washing machines, &c.
Patent GB-382969-A (GB)
Title: Manufacture of aromatic oxy-compounds and aromatic oxycarboxylic acids
IPC: C07C37/02
Filed: 1931-08-13
Abstract: Aromatic compounds containing nuclear halogen are heated under pressure with a carbonate or bicarbonate, preferably with the introduction of carbon dioxide and the aromatic oxy-compound and the oxy-carboxylic acid formed are separated from the reaction mixture. The carbonate may be replaced by the corresponding base and carbon dioxide.  For continuous operation it is advantageous to use potassium carbonate rather than sodium carbonate.  In examples (1) chlorobenzene is heated under pressure with an aqueous solution of sodium bicarbonate and the reaction mixture is extracted with benzene; the aqueous solution is concentrated, freed from sodium carbonate and bicarbonate and acidified to obtain the oxycarboxylic acids.  (2) Chlorobenzene is heated under pressure with an aqueous solution of potassium carbonate in the presence of copper, the oily layer containing unconverted chlorobenzene, phenol and diphenylether being removed; the aqueous alkaline liquid is concentrated by distillation under reduced pressure, freed from separated inorganic salts and acidified to obtain the oxycarboxylic acids.  (3) Chlorobenzene is heated with a solution of anhydrous sodium carbonate in the presence of copper under a pressure of carbon dioxide; the reaction mixture is worked up as in example (2).  (4) Chlorobenzene is heated with an aqueous solution of anhydrous sodium carbonate in the presence of copper and under a pressure of carbon dioxide; phenol, diphenyl ether and chlorobenzene are removed by releasing the pressure and distilling the mixture under reduced pressure; inorganic salts which have separated are removed from the residue and the oxycarboxylic acids are removed as the basic calcium salts.  (5) a -Bromonaphthalene is heated under pressure with an aqueous solution of anhydrous sodium carbonate and the reaction mixture is worked up to yield a -naphthol, a -naphthol ether, and a -naphthol carboxylic acids.  (6) b -chloronaphthalene is heated under pressure with an aqueous solution of sodium bicarbonate in the presence of copper and the reaction mixture is worked up to yield b -naphthol, the corresponding naphthyl ether and b -naphthol carboxylic acids. (7) Chlorobenzene is heated with caustic soda and carbon dioxide under pressure.
